Question

A cylinder has a surface area of 234π meters with a radius of 9 m. What is the volume of the cylinder? Leave your answer as π

Answer 1

Explanation:

surface area of cylinder=2
`\pi`rh

or,234
`\pi`=2*22/7*9*h

or,234*22/7=396/7*h

or,5148/7=396/7*h

or,36036=2772h

or,36036/2772=h

h=13

now,

volume=
`\pi`r^2h

=22/7*(9)^2*13

=3309.4285
